Hello,
I have a production environment working with 2 Cisco 6500 series configured as VSS. We have One supervisor and multiple SVI interfaces on MSFC card. Each of the two 6500 has one FWSM module mount but not configured. I have 45 SVI interfaces (VLAN) and I want to filter traffic between them.
I have tried to log on FWSM and configure management access (SSH, ASDM) but I am not able to ping the 6500 switch and I am not able to ping the FWSM on 6500.
Receive the configure of the FWSM. Only one FWSM have been configured.
FWSM Version 3.1(10)

On the 6500, I have done this:
6500(config)#firewall multiple-vlan
6500(config)#firewall switch 1 module 7 vlan-group 1 17,9
6500(config)#firewall switch 1 slot 7 vlan-group 1
6500(config)#interface vlan 9
6500(config-if)#ip address 10.100.1.254 255.255.255.0
6500(config-if)#exit
6500(config)#interface vlan 17
6500(config)#ip address 10.100.17.254 255.255.255.0
6500#ping 10.100.17.253
no answer
fwsm#ping 10.100.17.23
success
fwsm#ping 10.100.17.254
no answer .
Any helps would be really apreciated.

In a transparent mode firewall (FWSM or otherwise), both the inside and outside VLAN should be on the same subnet.

Thanks you,
Please what are the best steps to get ip connectivity between FWSM and 6500 while virtualized ?
Just to connect for management. What are the good steps after, to implement the FWSM in failover mode and to manage 46 SVI(Vlans). Transparent firewall is not an issue because it only uses 2 (vlan) pper BVI. the best practice please

Best practices are not explicitly defined for your particular configuration. I would just follow the configuration guide and consult the configuration examples on the product support page.
Note that the FWSM limits you to 8 bridge groups in a given context. To support the number of VLANs you're talking about, you'd need to be licensed for and run in multiple context mode.
One other thing you should consider (assuming you still have maintenance coverage on this product that hasn't been sold for over two years) is to upgrade your software. You are running 3.1(10) from April 2008 and there were 10 later maintenance releases just in the 3.1 train. The last release for the FWSM was 4.1(15) from October 2013.

Thanks you very much, I will first try to update the firmware. Please there is no adjustment in my configuration to get Ip connectivity with the 6500 ? in routed or transparent mode.
I just to want to get Ip connectivity and ASDM and SSH working fine.
Thanks,
